VEHICLE SFRING.

Application filed May 16, 1925. Serial No. 30,808.

To all fro/'mm t may concern:

Be it known that I, Lno (l. IIALnnn, a citizen of the United States, residing at Cercsco, county oi? Calhoun, State ot Michigan, have invented certain new and useful ImproveH ments in. Vehicle Springs, of which thel following is a specification.

This invention relates to improvenients in vehicle springs. 1

The main object ol the invention is to provide an k,auxiliary attachment tor a. semielliptical leal spring of amotor vehicle, such as a Ford, which increases resiliency and which also serves to a considerable degree as a shock absorber.

A further object is to provide such a structure -having these advantages which may be applied as an attachment without change in the spring structure of the automobilerand with very little adaptation otherf wise, particularly in a Ford automobile as now put outby the manufacturer.

Objects pertaining to details and economies of construction and operation will appear from the detailed description to follow.

I accomplish the objects of the invention by the devices and means described in the specification. The invention is pointed out and defined in the claims. A structure which is a preferred embodiment of the invention is illustrated in the accompanying drawing, forming a part of this application, in which Fig, I is a detail elevation view of one of my improved spring structures as applied to the front spring and axle ot a Ford automobile.

Fig. II is a similar detail view of the structure as applied to the rca-r spring and axle of Such an automobile.

Fig. III is a plan view of the lever part of my improved spring attachment.

Fig. IV is a perspective view of my improved structure as applied to the rear spring and axle oli such a vehicle. the parts oi the vehicle and main spring being indicated by dot-ted lines.

Fig. V is a similar detail perspective view oit the structure as applied to the -front axle and sprin g, the axle, perch and main spring being indicated by dotted lines.

Fig. VI is an enlarged detail transverse sectional view taken on line 6 6 of Figs. II, III and IV, showing the detail of construction and connection of the perch to the brake flange of the rear axle.

Fig. VII is a detail sectional view taken on line 7-7 ot Figs. II, Ill and IV. show ing the connection of the main arm or lever part to the end of the main spring by thc usual shackle.

In the drawing the sectional views are taken looking` in the direction ot the little arrows at the ends of the section lines and similar numerals ol reference relier to similar parts throughout the several views.

The parts will be identi lied bv their numbers. 1 is the main front axle. 2 is a hall" .ft one oit' the main semielliptical springs. 3 is the perch on the front axle.` 1 is the hifiurcatcd lever arm oi my inu'n'ov-ed spring, pivotally connected at 5 to the perch and connected by the spring shackle 6 by pivot 7 at an intermediate point on the lever to the end of the main spring. rllhe .inner end of the'arm is bifurcated at 8, 8. The yoke 9 is disposed above the same and is secured yieldingly toV the bifurcated arms 8, 8 by the vertical bolts 10, one at each side. A pair of springs 12 are disposed above the yoke 9 on the bolts 10 and are retained in place at their upper ends by thevcross arms 11 secured to the upper ends of the bolts 10 by the nuts 11. A pair of coil springs 13 are disposed below the biturcated arms 8. 8, and are retained in place by washers 111 and nuts 15.

The rear springs are similarly constructed except that the arms 4; are pivoted at 5 to porches 3 which are secured by bolts 16 and castcllated nuts 17 (see Fig. II) to the brake flange 18 of the rear axle. It will thus be seen that the difference between the front and rear structure is merely in the mattei' ot the design and arrangement ot the perch. A perch somewhat longer than is used :for connecting the usual sen'ii-elliptical spring shackle projects above the brake flange on the rear axle to ailord the connection. Comparatively long coil spring structures are usuable in this way iu a very compact relation. These coil springs yield very readily in advance of the action of the main spring. The yoke, which is upset and extends over and coacts with the top ot the leaf spring, slides very readily on and permits very free movement of the bolts therethrough, which are keptin perfect alinement by the cross bar at the top. "When the spring acts, the bifurcated arms compress the lower sections 10 of the spring, carrying the bolts down, and thus compressing also the upper sections l2 of the spring. This` insures complete flexibility and permits the shock ol? a sudden iolt to be absorbed Without its beine` transinitted to the niain spring, and at the saine linie adds to the fl. ility ot the main spring, as will be readily understood troni an inspection of the dran/'ing'. he coinpressed springs promptly return the niain spring' to normal after absorbingy the jolt.

The arrangement I have illustrated is very con'ipact and Well adapted to the limited space in which it inust he used. I desire to claim the invention specifically as illustrated and also broadly, as pointed out in the appended claims.

Having thus described iny invention `what I elaiin as nen7 and` desire to secure by Ilettcrs liatent is:

l. In a structure of the class described, the combination with the axle, of a perch carried thereby, a leaf body spring. a lever bifurcated at its inner end and pivoted at its outer end on the said perch and extendinglaterally at its inner end to each side of said body spring, vertical bolts disposed through the ends ol the bifurcations, a yoke connecting` the bolts together, offset to engage the top of seid bo( y spring, coiled springs disposed both above and below the said biliurcated :irins on said bolts, a tie bar for the upper ends o'l said bolts., and a shackle connecting an intermediate part of the said arm to the end oi' said body spring, coacting as specilied.

2. In a Structure of' the class described, the combination with the axle, of a perch carried thereby, a seini-ellii'itieal body spring, a lever pivotally mounted on said perch suitably bi- `fur `ited and extendinf out laterally at each side oi the said body spring, a vertical bolt disji'iosed through the outer end ot each bifureated arin, a yoke for said bolt in proxin'iity to the said bifurcated arin, a tie bar at the upper end of said bolts, and pairs ot springs above the said yoke and below the said bifurcated arms, and a shackle link connectiirethe end of the body spring` to an intermediate partof the lever, coactingr as specilied.

In Witness whereof I have hereunto set iny hand.
